Voters in Wisconsin's 7th Congressional District face a three-way race to elect a representative in the U.S. House of Representatives. Incumbent Rep. Sean Duffy, R-Wis., is facing challenges from Democratic candidate Margaret Engebretson and Ken Driessen of Hayward, who is running as an independent favoring direct participatory democracy. Driessen said he's signed an affirmation pledging to seek people's opinions on the issues that come before Congress to the best of his ability.
